Μελέτη μεθόδων μη παραμετρικής φασματικής ανάλυσης για την απεικόνιση εναέριων στόχων με την χρήση ραντάρ αντίστροφης συνθετικής απεικόνισης [PDF]

open access: yes, 2014
Αντικείμενο της διατριβής αποτελεί η μελέτη της απεικονιστικής τεχνικής του ραντάρ αντίστροφης συνθετικής απεικόνισης (Inverse Synthetic Aperture Radar - ISAR) με την χρήση μεθόδων μη παραμετρικής φασματικής ανάλυσης. Οι μέθοδοι που εξετάζονται είναι οι μέθοδοι μη παραμετρικής φασματικής ανάλυσης CAPON και APES, ο αλγόριθμος εκτίμησης φασματικών ...

Sparse representation for the ISAR image reconstruction [PDF]

open access: yes, 2016
In this paper, a sparse representation for the data form a multi-input multi-output based inverse synthetic aperture radar (ISAR) system is derived for two dimensions.

Advanced studies of electromagnetic scattering [PDF]

open access: yes
In radar signature applications it is often desirable to generate the range profiles and inverse synthetic aperture radar (ISAR) images of a target. They can be used either as identification tools to distinguish and classify the target from a collection ...

Geniş bant - geniş açı ters yapay açıklıklı radar (TYAR) görüntüleme algoritması geliştirilmesi ve nümerik uygulamaları

open access: yes, 2020
Inverse Synthetic Aperture Radar (ISAR) is a powerful signal processing technique for imaging moving targets in range and cross-range domains. In this thesis, scattering EM field is collected within a wide band ? wide angle range. If this is the case, FFT method cannot be readily used for 2D ISAR imaging application.

Autofocus for ISAR Imaging Using Higher Order Statistics [PDF]

open access: yes
Autofocus is imperative for inverse synthetic aperture radar (ISAR) imaging. In this letter, a new approach for ISAR autofocus is developed by using fourth-order statistics properties of the radar’s return signal.
